Abstract
In a divider, a ratio of a magnification or a reduction of an image is set from a writing range and a reading range. In a horizontal interpolating circuit and a vertical interpolating circuit, an interpolation is performed on the basis of the magnification ratio. In the horizontal interpolating circuit and the vertical interpolating circuit, an interpolation is performed on the basis of the reduction ratio. In a field memory, a portion of the image of an arbitrary size at an arbitrary position is written on the basis of a control signal which is supplied from a write memory control circuit. The image is read out from the memory on the basis of a control signal which is supplied from a read memory control circuit.
